3 Claims. 1

The invention relates to measuring and dispensing cans.

One object of the invention is to provide an improved can for oil which is adapted to measure and dispense predetermined quantities of oil for mixing oil with gasoline for use in internal combustion engines, such, for example, as outboard motors.

Another object of the invention is to provide a can of this type which is simple in construction, which includes a piercing and measuring tube which may be left in the can and used to pour predetermined volumes of oil from the can.

Other objects of the invention will appear from the detailed description.

The invention consists in the several features hereinafter set forth and more particularly defined by claims at the conclusion hereof.

In the drawings:

Fig. 1 is a longitudinal section of a can embodying the invention with the pouring and piercing tube therein, the closure cap on the tube.

Fig. 2 is a section taken through the top ofthe can before the pouring and piercing tube has been inserted into the can.

Fig. 3 is a section of the can inverted for pouring the first measured volume of oil from the can.

Fig. 4 is a section illustrating a modified form of invention.

The invention is exemplified in a can which is usually formed of sheet metal and comprises a bottom it, a top II, a cylindrical side l2, all of which are permanently secured together to form a closed body, for containing a supply of oil, for example, a quart.

The top H is depressed to form an integral annular wall M and a ledge H3 at the inner end of wall it. The top is also formed with an integral cup-shaped member and includes a depending sleeve it of lesser diameter than the annular wall H1 and a bottom I! which is adapted to be pierced or punctured downwardly for the removal of the oil from the can. A ring Id of sealing material, such as vellumoid is seated on the ledge l5 between the annular wall l4 and is provided with a central opening 255 co-axial with the cylindrical side wall it of the cup-shaped member. A disk 22 is substantially flush with the outer portion of the top H] and is secured, for example, by solder, as at 23 to the upper portion of wall Hi and is adapted to retain the sealing ring l8 confined in the chamber between ledge l5 and said disk. Disk 22 is provided with a central opening 24 which is substantially of the same diameter and co-axial with the inner diameter of the sleeve 16 of the cup-shaped member.

A cylindrical piercing and pouring tube 26 has an inclined annular lower end 2? which is adapted to punch out the bottom I! of the cup-shaped member when it is driven therethrough. Tube 26 passes through the opening 24 in disk 22 and the opening in the sealing ring l8 and slidably fits in sleeve l6 of the cup-shaped member. The cylindrical wall I6, while the tube 26 is being driven or moved into and out of the can, guides the tube rectilinearly so that it will be co-axially positioned in the can and maintained in such position while it is in different positions in the can. A cap 28 fits over the outer open end of the tube 26 to form a closure for the tube after it has been inserted in the can and between uses. The tube has lines 29 thereon for indicating the elevation of the oil in the can. Tube 26 serves as a tube through which the predetermined volume of oil may be successively poured, and also as a punch for severing the bottom I? of the cupshaped member from the top I I.

Oil is kept sealed in the can until it is to be used. When it is desired to use a quantity of oil in the can, the tube 26 is inserted in opening 24 in disk 22 and in the opening in sealing ring it? and into the sleeve l6 of the cup-shaped member by which the tube will be guided rectilinearly and axially. Tube 26 is then forced downwardly so that its lower inclined end 2! will punch out the bottom I1. When the bottom ll is punched out, the tube will be communicatively connected with the oil in the can so that oil can be poured out by inversion of the can with the tube therein.

When the can contains a full supply of oil, tube 26 is positioned with its lower inclined end 27 close to the bottom of the can. The can is then completely inverted, as illustrated in Fig. 2, and oil will be discharged through tube 26 until the level of the oil drops to the level of the lowest portion of the opening through the inclined end 21 of the tube so that a limited volume of oil will be discharged from the tube. Tube 26 may be left in this position and closed with cap 28 thereon until the next use. When another charge of oil is desired, tube 26 will be raised until the next line 29 is positioned at the disk 22. The can is then again completely inverted and oil will be discharged through the tube until it drops to the level of the lower end of the opening in the inclined end 21 of the tube, so that another limited volume of oil will be discharged. For each successive use, tube 26 will be raised according to the next line indication and a limited quantity will be discharged upon inversion of the can. when oil has been discharged from the inverted can until the level of the oil drops to the level of the inner end of sleeve It, a quantity of oil will be retained in the can which will not be discharged through tube 26 when the can is inverted. The sp cing between the line indications 29 is grs to compensate for Variations in the height of the column of liquid in the tube 26, during the pouring of each charge, as the column of liquid in the can progressively increases.

The purpose of providing the can with the cupshaped member of the desiredheight to retain the last charge of oil is to make it necessary to puncture the can in order to pour out the last charge. By making it necessary to puncture the sealing ring 18, and the cup-shaped member including the cylindrical sleeve it and its integral bottom H, are formed of a single piece of drawn or spun metal, separately from the top of the can. The annular wall Id is provided with an outwardly extending flange 3b which is soidered or welded to the inner face of the top H of the can. The opening 2d for the piercing tool is formed in an integral portion of the top l l which is extended as at i l to confine the sealing ring 53.

The invention exemplifies a can for measuring and dispensing oil in predetermined quantities, which is simple in construction and advantageous in use. The sleeve of cup-shaped member depending from the central portion of the top of the can below the sealing ring serves to guide the tube rectilinearly between its several positions in the can and while the bottom H is being punched out to open the can. It also functions to retail a volume of oil sufiicient for one charge in the can, which cannot be removed through the tube, so that the can will be disposed of after the removal of the last charge.

The invention is not to be understood as limited to the details described, since these may be modified within the scope of the appended claims without departing from the spirit and scope of the invention.

Having thus described the invention, what we claim as new and desire to secure by Letters Patent is:

1. The combination with a sheet metal can for measuring and dispensing liquids, the can including; a bottom, a substantially fiat top, and a surrounding side, all permanently joined together, an annular wall extending into the can, 7
